SoundPool 不播放声音
我制作了一个 SoundManager 类，它使用 SoundPool 函数来循环特定的声音，但是我不明白为什么它不播放声音。
public class SoundManager {
private SoundPool mSoundPool;
private HashMap<Integer, Integer> mSoundPoolMap;
private AudioManager mAudioManager;
private Context mContext;
public SoundManager()
{
}
public void initSounds(Context theContext) {
mContext = theContext;
mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);
mSoundPoolMap = new HashMap<Integer, Integer>();
mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
}
public void addSound(int Index, int SoundID) {
mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1));
}
public void playSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f);
}
public void playLoopedSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, -1, 1f);
}
这个
类是通过我的 Activity 调用的：
private SoundManager mSoundManager;
mSoundManager = new SoundManager();
mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(1, R.raw.sound);
mSoundManager.playSound(1);
I made a SoundManager class that uses SoundPool functions in order to loop a specific sound, however I can't figure out why it isn't playing a sound.
public class SoundManager {
private SoundPool mSoundPool;
private HashMap<Integer, Integer> mSoundPoolMap;
private AudioManager mAudioManager;
private Context mContext;
public SoundManager()
{
}
public void initSounds(Context theContext) {
mContext = theContext;
mSoundPool = new SoundPool(4, AudioManager.STREAM_MUSIC, 0);
mSoundPoolMap = new HashMap<Integer, Integer>();
mAudioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
}
public void addSound(int Index, int SoundID) {
mSoundPoolMap.put(Index, mSoundPool.load(mContext, SoundID, 1));
}
public void playSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, 0, 1f);
}
public void playLoopedSound(int index) {
int streamVolume = mAudioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
mSoundPool.play(mSoundPoolMap.get(index), streamVolume, streamVolume, 1, -1, 1f);
}
}
This class is being called from my Activity via:
private SoundManager mSoundManager;
mSoundManager = new SoundManager();
mSoundManager.initSounds(getBaseContext());
mSoundManager.addSound(1, R.raw.sound);
mSoundManager.playSound(1);

显然它对我的活动不起作用，但在事件发生时调用它（意图/按键）它似乎起作用
Apparently it doesn't work onCreate for my activity but calling it when an event happen (Intents / Keypress) it seems to work
我遇到了这个问题，最后通过在支持音频的模拟器上运行解决了它！
不敢相信事情就这么简单！
窗口> AVD管理器>编辑您的 AVD（为了安全起见，我创建了一个新的 AVD，因为我是从快照运行的）>硬件>新的>音频播放支持
I had this problem and finally solved it by running on an emulator that supported audio!!
Can't believe it was that simple!
Window > AVD Manager > Edit your AVD (I created a new one to be on the safe side cause I was running from snapshot) > Hardware > New > Audio Playback Support
